Practice Units

 

As part of LB&I's knowledge management efforts, Practice Units are developed through internal collaboration and serve as both job aids and training materials on tax issues. For example, Practice Units provide IRS staff with explanations of general tax concepts as well as information about a specific type of transaction. Practice Units will continue to evolve as the compliance environment changes and new insights and experiences are contributed. Please visit this site periodically for new and updated Practice Units which are shared below.

To provide feedback on a specific Practice Unit, please send an email to LBI Practice Unit Public Feedback and specify the Practice Unit's name and Document Control Number (DCN), which are both listed on the Practice Unit's cover page. Please do not reference a specific individual or entity in your email as comments may be subject to future release. The IRS does not commit to respond to suggestions or comments.

Practice Units are available in Adobe PDF and must be viewed with the Acrobat Reader.

Note: Practice Units are not official pronouncements of law or directives and cannot be used, cited or relied upon as such. Practice Units provide a general discussion of a concept, process or transaction and are a means for collaborating and sharing knowledge among IRS employees. Practice Units may not contain a comprehensive discussion of all pertinent issues, law or the IRS's interpretation of current law. Practice Units do not limit an IRS examiner's ability to use other approaches when examining issues. Practice Units and any non-precedential material (e.g., a private letter ruling, determination letter, or Chief Counsel advice) that may be referenced in a Practice Unit may not be used or cited as precedent. References to third party service providers and documents, like news or journal articles, are for informational purposes only and do not constitute an endorsement of any vendor, document, or the services or views offered by such third party.
